 Homework Statement:

Given the plane: 4x  2y +8z = 8,
Find Parametric equations of the line of intersection of the given plane and the xzplane.
The answer for the question is: x = 2 +2t ; y = 0, z = t
I don't understand how to get to this answer and I am going to be tested on this type of question. Can anyone help me understand this please?
 Relevant Equations:

x = x1 + at
y = y1 + bt
z = z1 +ct
Sorry for the really messy work I know I have a problem.
The other questions that the problem asked before the one I need help with are as follows:
Find the intercepts and sketch the plane.
Find the distance between the plane and the point (1,2,3)
Find the angle between the plane and the xz plane
Thank you for any help you can give me
